A.H1:BBRLB. ORE PULVERIZER.

UNITED STATES PATENT GEEICE.

AUGUST HEBERLE, OF SALA, SWEDEN.

ORE-PULVERIZER.

SPECIFICATION forming part of Letters Patent No. 269,667, dated December 26, 1882 Application filed September 9, 1892. (No model.) Patented in Germany June 27, 1875!, No. 8,808, and in Austria-Hungary October 8, 1880, No. 15,814 and No. 30,037.v

To clL whom it may concern.-

Be itknown that I, AUG-usr HEBERLE, of Sala` Sweden. a subject of the King ot' Swe- `den, and resident at Sala, in the Kingdom of Sweden, have invented new and useful Improvernents iu Ore-Pulverizers, of which the following is a specification.

My invention relates to that class of machines or,in'ills in whit-h the reduction or disintegration ot' material is etl'ected by two rotary disks placed face to face, and between which thev material is fed.

My invention consists in a novel combination of parts, hereinafter described, including a hollow shaft or spindle for one ofthe grinding-disks and a pipe arranged in said shaft or spindle,and through which ore and water may be drawn into the space between the grindingdisks by the suction produced by the rotation of said disks.

In the accompanying drawings, Figure l represents al longitudinal section ot' a machine embodying my invention, and Fig. 2 representsa plan thereof.

The saine letters of reference designate corresponding` parts in both figures.

a designates a shaft or spindle, carrying fast and loose pulleys b c and the grinding-disk d.

e designates a hollow shaft or spindle. carrying the other grindiug-disk,f, and the shaft` e is supported in beatings e', which may be adjusted in planes pai allel with the l'ace of the disk, so that the two disks will be more or less eccentric to each other, as may be desired.

The bearings c are formed in a frame or stock, which is secured by bolts to a foundation plate or bed, and by loosening said holt-s provision is afforded for adjusting the frame or stock laterally to any extent to set the spindle e eccentrically to the spindle a.,and after it is so adjusted it may be secured by tightening said securing-bolts.

The outer end of the shaft or spindle c tits in an' oil-box, A, and bears against a thrust bearing or block, a', therein. The oil-box A has a bearing and is adapted to slide on two rods, I5, connected at their outer ends by a cross-bar, B', in which a sleeve or nut, a, is adapted to turn. The said sleeve or nut may be turned by a hand-wheel, g, applied to it.

C designates a screw, which is held by the I l oil-box A against rotation, but which may be moved longitudinally by turning the sleeve or nut n; and upon said screw is a shoulder,

(here represented as formed by anut, 45,) which bea-rs against a llange or abutment, D, au'd when the screw is moved toward-the right the said flange or abutment is moved toward the oil-box A. Between the oilbox A and the flange or abutment D is a spring, h. (Here shown as composed ot' disks ot' rubber.) When the screw C is adjusted toward the right the springhiscompressed and the grinding-disk d is pressed against the disk f with increased force, while when'the screw is adjusted toward the left the spring is relaxed, and the pressure ofthe disk cl on the diskf is decreased. A slight space is left between the thrust bearing or block c and the adjacent end of the screw U, and thus opportunity is afforded for the disk d to recede from the disk fit' too much material or too large pieces come between the disks. As soon as material is introduced between the disks the diskf will rotate by friction. Tithin the hollow axle e is situated the stationary pipe k, which,together with the hopper l, serves to introduce the inaterial, together with the necessary water. The gland m prevents any air entering along the outside ot' the pipe. The rapid motion ot' the disks will produce a suction through the pipe 7c, and the ore and the necessary amount ot' water will be caused to pass through the pipe into the space between the disks by atmospheric pressure.

What I claim as my invention, and desire to secure by Letters Patent, is s The combination, with the disk d and its shaft or spindle a, ot' the diskfand its hollow shaft or spindle e, and the pipe k, through which ore and water may be drawn into the space between said disks by the suction produced by the rotation of said disks, substantially as herein described.

In testimony whereof l have signed my name to this specitication in the presence of two subscribing witners'es.

AUGUST HEBERLE.
